Answer:

11.5 hours

Step-by-step explanation:

It would take Seith x hours to paint the room by himself, then Ted needs x + 1 hour.

During 1 hour, Seith can do 1/x of the work, Ted can do 1/(x+1) of the work, then we have

1/x + 1/(x + 1) = 1/6

(2x + 1)/[x(x+1)] = 1/6

x(x+1)=6(2x+1)

x^2 + x = 12x + 6

x^2 - 11x - 6 = 0

[tex]x=\frac{11+\sqrt{145}}{2}= 11.5 hours[/tex]

Answer:

120 children and 388 adults bought tickets for the swimming pool. Explanation: Create two simultanous equations:.

Put y = 2x - 7 into a graphing website and it'll show you (0, -7), (1, -5).

Zarab pay for all candies = 5x

Zarab pay for all cakes = 20 y

Total cost = 5x + 20y

Money spent = 5x + 20y

= 5 × 10 + 20 × 5

= 50 + 100

= $150

Answer: 310

Step-by-step explanation:

Multiplying a value by 1/10 is the same as dividing by 10.

Therefore, 3100* 1/10 = 3100/10

3100/10 = 310.

Hey there!

3,100 × 1/10

= 3,100/1 × 1/10

= 3,100(1) / 1(10)

= 3,100 / 10

= 3,100 ÷ 10 / 10 ÷ 10

= 310 / 1

= 310 ÷ 1

= 310

Therefore, your answer is: 310

Good luck on your assignment & enjoy your day!

Answer:

1. Undefined

2. Negative

3. Zero

4. Positive

Step-by-step explanation:

1. Undefined, the line moves in both directions vertically. It's impossible to tell what the slope is.

2. Negative, the line is decreasing at a constant rate, the slope is negative.

3. Zero, the line doesn't increase or decrease, therefore the slope is 0. (No changes)

4. Positive, the line is increasing at a large rate, the slope is positive.

Answer:

the volume should be 2/15

Answer:

24/5

Step-by-step explanation:

1 1/5 is equal to 6/5. 4 times 6/5 is first 4 times 6 which is 24 and then /5. So the answer is 24/5

Answer:

33.49 cubic inches

Step-by-step explanation:

the volume of a sphere is represented by (4/3)pi(r)^3

pi is 3.14 and r is 2

so 4/3(3.14)(2^3)

2^3 is also 8

4/3(3.14)(8)

the final answer is 33.4933333

OR when rounded it is 33.49

Statement:

The radius of the sphere is 2 inches.

To find out:

The volume of the sphere.

Solution:

[tex] = \frac{4}{3} \times 3.14 \times {(2)}^{3} \: \: cubic \: \: inches \\ = \frac{4}{3} \times 3.14 \times 8 \: \: cubic \: \: inches \\ = 33.49 \: \: cubic \: \: inches[/tex]

Answer:

The volume of the sphere is 33.49 cubic inches.

Answer:

900 batteries

Step-by-step explanation:

First we must find how many batteries does 1 calculator need

we can do this by dividing 160 by 40

which will give us 4 batteries per calculator

then we multiply the amount of calculators we have with 4

225×4 = 900 so we need 900 batteries

Answer:

She baked 640 cookies at first.

Step-by-step explanation:

Let cookies be x and muffins be y,

Let cookies remaining be z and remaining muffins be a

x = 264 + y

now,

x - 3/8 of x = z

x - 3x/8 = z

or, (8x-3x)/8 = z

so, z = 5x/8

Now,

y - y/2 = a

or, (2y-y)/2 = a

so, a = y/2

Now,

z + a = 588

or, 5x/8 + y/2 = 588

as we know x = 264 + y,

or, 5(264 + y)/8 + y/2 = 588

or, (1320 + 5y)/ 8 + y/2 = 588

or, (2640 + 10y + 8y)/16 = 588

or, 2640 + 18y = 9408

or, 18y = 9408 - 2640

or, 18y = 6768

so, y = 6768/18

so, y = 376

now,

x = 264 + y

or, x = 264 + 376

so, x = 640

Answer:

A= 0.5 x (a+b) x h

124 = 0.5 x (12+19) x h

124 = 15.5 x h

÷15.5

h = 8cm

0.5x(12+19) x 8 does gives 124

Thus, height is 8cm.

Answer:

Part A: 9.75x > 195

Part B: x > 20

Step-by-step explanation:

Let's say Mark works for x hours. For each hour he works, 9.75 dollars are added to Mark's salary. Therefore, for 1 hour, he gets $9.75, for 2 hours, he gets $9.75 + $9.75 = $9.75 * 2 = $19.50, and for x hours, he gets $9.75 * x as his salary.

We want his salary to be more than $195, so we have $9.75 * x (his salary) > $195, which can be written as 9.75x > 195

divide both sides by 9.75 to solve for x

x > 20

Answer:

4

Step-by-step explanation:

yes 1x is the same a x Technically the 1 front of the x is called implied so it's simply written as x say x=4

Answer:

5/9

Answer:

yes they are all functions

Step-by-step explanation:

Despite f(x) being the classic way to write a function,

a function has:

A function relates each element of a set with exactly one element of another (possibly the same) set.  

One-to-one and many-to-one are functions, but one-to-many is not a function.

You can also carry out the Vertical Line Test on a graph.  If the vertical line only crosses the curve once, it is a function.  If it crosses more than once it is still a valid curve, but is not a function.

Yes they all are functions

Functions should include
